2. Arteries Veins Carry blood AWAY from the heart
All BUT pulmonary arteries carry oxygenated blood
Aorta: largest artery; 1 inch in diameter
Arterioles: smallest arteries
Coronary arteries: most important; supply blood to the heart muscle
Carry blood TOWARD the heart
All BUT pulmonary veins carry deoxygenated blood
Layers much thinner, less elastic
Series of internal valves that work against the flow of gravity to prevent reflux
Superior and inferior vena cava: largest veins
Venules: smallest veins

3. Capillaries Tiny, microscopic vessels Walls one cell layer thick
Function: to transport and diffuse essential materials to and from the body’s cells and the blood

4. Did you know…
You have approximately 100,000 miles of blood vessels in your body
Enough to circle the earth 4 times

5. Cardiovascular Cycle
20% of blood leaving heart goes to the brain

6. Coronary Arteries Coronary arteries supply the heart with oxygen
If one or more become blocked, a heart attack can occur.
Bypass surgery is grafting arteries and veins taken from others areas the body to “bypass” or restore circulation to the blocked coronary artery

7. Coronary Artery Disease
Atherosclerosis – narrowing and stiffening of arteries due to fatty deposits
Angina – chest pain relieved by rest, sign of inadequate blood supply to heart
Heart Attack – (MI or Myocardial Infarction) cardiac muscle deprived of blood and oxygen due to a blocked artery

9. Narrowed artery with balloon catheter positioned.
Percutaneous transluminal coronary angioplasty is a surgical procedure in which a balloon catheter is inserted into a blocked blood vessel to increase the blood flow of that vessel.
Narrowed artery with balloon catheter positioned.
Inflated balloon presses against arterial wall.

10. Circulatory Disorders
Embolism – material that breaks away from its original site that causes a blockage
Thrombosis – blockage of an artery or vein due to a blood clot
Aneurism – abnormal swelling of a weakened arterial wall that makes it bulge out like a balloon

11:40-12:20
19:30-21:40 removed
24:15 to 25:59 new heart
47.25 to 49 new heart begins to beat
